وَإِذَا خَلَوْا إِلَى شَيَاطِينِهِمْ قَالُوا إِنَّا مَعَكُمْ
When they are alone with their devils, they say: We are with you.
In the Qurʾānic passage, the words following “qālū” are reported as the hypocrites’ own speech. To judge the connection with what follows, one must ask whether the next utterance belongs inside that quotation or is an independent report made by the narrator.
Quoted speech and the narrator’s own assertion have different speakers and different functions. A connector that accidentally moves a narrator’s statement into the quoted speech changes the meaning. This shows why syntactic and discourse roles must be considered together.
